| Question | Answer |
|---|---|
| Anther | A sac-like structure at the tip of the stamen in which pollen grains are produced. |
| Apical Meristem | The growing point in a vascular plant at the tip of a shoot or root where cell division occurs. |
| Calyx | The whorl of sepals. |
| Carpel | The female reproductive part of a flower consisting of the stigma, style, and ovary. |
| Club Moss | The earliest group of seedless vascular plants. |
| Cone | The ovulate strobilus on gymnosperms that contains ovules. |
| Conifer | The dominant division of gymnosperms with the most variety of species. |
| Corolla | The collection of petals in a flower. |
| Cotyledon | The one (monocot) or two (dicot) primitive leaves present in a seed. |
| Cycad | A division of gymnosperms that grow in tropical climates and resemble palm trees. |
| Dicot | A group of angiosperms whose embryos possess two cotyledons; also known as eudicots. |
| Eudicots | A group of angiosperms whose embryos possess two cotyledons; also known as dicots. |
| Fern | A seedless vascular plant that produces large fronds; the most advanced group of seedless vascular plants. |
| Filament | The thin stalk that links the anther to the base of the flower. |
| Gametophyte | The haploid plant that produces gametes. |
| Gingkophyte | A division of gymnosperm with one living species, Ginkgo biloba, a tree with fan-shaped leaves. |
| Gymnosperm | A seed plant with naked seeds (seeds exposed on modified leaves or in cones). |
| Herbaceous | Describes a plant without woody tissue. |
| Hornwort | A group of nonvascular plants in which stomata appear. |
| Horsetail | A seedless vascular plant characterized by a jointed stem. |
| Liverwort | The most primitive group of nonvascular plants. |
| Monocot | A related group of angiosperms that produce embryos with one cotyledon and pollen with a single ridge. |
| Moss | A group of plants in which a primitive conductive system appears. |
| Nonvascular Plant | A plant that lacks vascular tissue formed of specialized cells for the transport of water and nutrients. |
| Ovary | The chamber that contains and protects the ovule or female megasporangium. |
| Petal | A modified leaf interior to the sepal; colorful petals attract animal pollinators. |
| Phloem | The vascular tissue responsible for transport of sugars, proteins, and other solutes. |
| Pistil | The group of structures that constitute the female reproductive organ; also called the carpel. |
| Sepal | A modified leaf that encloses the bud; outermost structure of a flower. |
| Sporangium | The organ within which spores are produced. |
| Sporophyte | The diploid plant that produces spores. |
| Stamen | The group of structures that contain the male reproductive organs. |
| Stigma | The uppermost structure of the carpel where pollen is deposited. |
| Strobili | Cone-like structures that contain the sporangia. |
| Style | The long, thin structure that links the stigma to the ovary. |
| Syngamy | The union of two gametes in fertilization. |
| Vascular Plant | A plant in which there is a network of cells that conduct water and solutes through the organism. |
| Whisk Fern | A seedless vascular plant that lost roots and leaves by evolutionary reduction. |
| Xylem | The vascular tissue responsible for long-distance transport of water and nutrients. |
